In this Geometry Nodes 3.1 tutorial, I'll show you how to represent animated blood cells or platelets flowing through a vein. You can control the speed of the red platelets with Geometry Nodes, as well as their number and rotation speed. The vein itself can be changed in shape and length by editing a path. The materials of the platelets and the vein are 100% procedural. This tutorial is part of the "Blender for Scientists" series.
